Specification of Letters Patent.

Patented Dec. 25, 1906.

Application filed September 16,1904. Serial No. 224,764.

To all whom;v it mrty concern:

Be it known that I, yVILLIAM' R. Fox, a

i citizen of" the United States, residing at the city of Grand Rapids, county of Kent, State `of Michigan, have invented certain new and useful Improvements in Tabulator's for Type- Writcrs, of whichthe following is a specification.

Y This invention relates to improvements in tabulators for type-writing machines'.

It relates to the style of tabulator for which Iapplied for Letters Patent on May 6, 1904, Serial No. 206,684, and to certain improve- .ments independent of those describedor re- "ferred .to in the said a plication. With' the eculiar' form of tabu ator described in my ormer patentapplication a little care is kre- (pired in the operation of the same, else if t 'e carriage-stop happened to be over the notched tabulator-stop this tabulating might not be entirely accurate, and it was therefore necessary to "take painsthat the carriage be moved toward the starting-point a sui'licient distance to insure that the carriage-sto be entirelyv beyond the notched tabulator-plate This was never noticed in the ordinary operation of themachine; but when theV machine .Was in the hands of beginners they might encounter difIiculties of this kind.

The objects of this inventionl are, first, to

provide" an improved tabulatoi' in which thedefect above referred to is overcome second, to provide an improved construction of the connections for the tabulator-stop; third, to provide ankv improved means of preventing the release of the carriage except when the tabulator is operated; fourth, to provide an improved means of releasing the escapem'ent` j during the process of tabulating.

invention is clearly il Further objects and objects relating to structural details will definitely appear fromA ythe detailed description to follow.

I 'accomplish the objects of my invention by the devices and means describedin the .following specification. l

The invention is clearly defined, and pointed out in the claims.

Fig. 8 is an enlarged detail sectional view taken .on line k8 8 of Fig. 3, showing the tabulator release-bar D and its connection to the connecting-rod D. taken on line 9` 9 of Fig. 3, showing the arrangement ofthe tabulator-bar and whereby it'swings the tabulator locking mechanism out of engagement and permits the releasebar to release the carriage. Fig. 10 is a detail sectionalview taken on line 10 10- of Fig. 3, showing the method by which the releasebar is locked, exe t when one of the tabulator-keys is ushe in.' Fig.` 11 is a vertical' transverseetail sectional elevation view of the tabulating-key connections, taken on a line corresponding to line 11 11 of Figs. 1 and 3. Fig. 12 is 'an enlarged detail view of one of theadjustablestops U.

In the drawings, similar letters of reference refer to similar parts throughout the several views, and the .sectional views are taken looking in the direction of the little aring machine, the top lplateA being in the Fig. 9 is a detail sectional viewl IOO usual form and bearing acarriage M on sui-ti able ways N B is a removable toe-piece across the front of themachine, servin to sup ort the Vfront ends or buttons I of t e keysli of the tabulator mechanism and the connecting-rods D for the release-bar D, which reci rocate through suitable bearings therein. transverse bar B isvs'ulp orted by forwardly-extending arms B- B fiom this removablet'epiece, Vand the tabulator-rodsare through tapertures in this bar and are adapted to reciprocate therethrough.

Alever m is'provided and fulcrunied on e glpivot on the o'set portion of the rock-shaft ),Whieh carries the-escapenient mechanism, and the connecting-rod 71l is connected to the end ofit.

On this uniehine the tnhulstor is divided into three sections having three independently-movable vertical notched lmrs y g y", as appears in Figs. 2 and 3.
